But instead, the device turns on (nearly) instantly. Because the wire isn’t actually what causes the device to turn on
That’s not exactly true. In this case, the energy transmission would go like this: (change of electric field in the little bit of wire next to the power source) -> (change of magnetic field in the air between the wires) -> (change of electric field in the wire next to the load). This limits the amount of energy transmitted significantly and incurs a lot of losses, meaning if you had something like a lamp plugged in it would start glowing extremely dimly at first (think about how some cheap LED lights keep glowing even with the switch off - it’s similar, albeit it happens due to inter-wire capacitance and not induction). It would then slowly ramp up to full power over a course of a year.

Here’s a video from the same person about it: https://www.youtube.com/watch?v=2Vrhk5OjBP8 (although I haven’t watched this yet)
